What “cut to size” really means for blinds
When people ask for, they often mean having the right measurements turned into a finished blind without guesswork. “Cut to size” typically covers both the width of the headrail and the height of the fabric or slats, depending on the blind type. Before any cutting is done, bunnings blinds cut to size the installer checks the mounting surface, the window recess, and the clearance needed for the blind to operate smoothly. This matters because a blind that is even slightly too wide or too long can bind in the mechanism or leave gaps around the edges.
Cutting also needs to match how the blind is meant to function. For roller blinds, the fabric height and the operating chain or wand length affect how the blind lands at the top and bottom. For venetian or vertical styles, the spacing and slat length influence tilt range and how the blind stacks when retracted. A practical approach is to decide whether you want an inside-mount (inside the recess) or an outside-mount (on the wall or above the recess), since each method changes the measurement rules. Using the correct mounting style prevents common issues like misalignment, uneven edges, and difficult lifting.
How to measure accurately before you order
Start by choosing the mount type and measuring the space where the blind will sit. If you are doing an inside mount, measure the recess width at three points and use the narrowest measurement, then measure the recess height at three points and use the shortest measurement. If you are doing an outside mount, add appropriate overlap on both bunnings roller blinds cut to size sides and enough height so the blind fully covers the window area when closed. Keep the tape straight and record measurements in millimetres to reduce rounding errors. For a clean result, note any obstructions such as window handles, crank mechanisms, architraves, or cornices that can interfere with the headrail.
Next, confirm how the blind will be installed and what clearance is required for the brackets and chain path. Some window frames sit unevenly, so checking plumb and level helps you avoid a blind that looks crooked even if the numbers are correct. If the window is not square, you may need to refine the measurement strategy to ensure the blind remains parallel to the opening. For, the fabric needs to be cut with enough allowance to roll neatly on the tube without leaving too much slack. A good practice is to double-check the usable height from where the headrail will sit to where you want the bottom edge to finish.
Practical ordering and installation tips for a perfect fit
Before you finalise your order, confirm which parts are being made to your measurements and which components are standard. Many blinds include standard brackets, tubes, and operation hardware, but the fabric length, rail position, and sometimes the light-control components depend on your measurements. Ask for guidance on whether your chosen fabric is cut to the measured height or requires an extra adjustment for the hem or bottom bar. If you have an uneven floor or slightly sloped recess, plan for how the bottom edge should sit when fully lowered. Detailing these points avoids surprises during installation and helps the blind close cleanly.
During installation, alignment is the difference between “almost right” and a professional finish. Mark bracket positions using a level, then test the blind operation before fully tightening everything. If you are mounting in a recess, ensure the headrail clears the frame and that the side edges don’t rub on the trim. For roller blinds, check that the fabric rolls evenly without telescoping, which can happen when the tube is not aligned. After fixing, run the blind up and down several times to confirm smooth travel, then fine-tune bracket positions if needed. When you want a practical outcome, plan for small adjustments and treat the measuring and mounting steps as a single coordinated process.
